Norman used to be in a divided tank with Walter, but he couldn't stand being able to see another fish's shadow through the divider, and chewed his fins down to nubs. They're starting to grow back, as you can see:
...but I'm wondering about the top/front ray on his dorsal fin. It's hard to see from the photos (Norman NEVER stops moving, so it's hard to get clear shots of him), but there are two kinks in it, one close to his body and one closer to the end. It's circled here:
Will that repair itself as the fin grows back, or did Norman permanently mutilate himself? Not that I really mind either way; he's a spaz but I love him anyway.

Just curious if it will heal normally.
(P.S. Norman doesn't have ich, I swear. I just need to clean the front of my tank. ;)
